A shock absorbing lanyard is a one-piece webbing. The shock absorbing lanyard has a tubular-shaped high strength outer sheath and a high elongation member inside of the outer sheath. The outer sheath and the high elongation member are secured together at spaced apart connection locations and the high elongation member is generally not secured to the outer sheath between the connection locations. Heat treatment shrinks the length of the high elongation member. The outer sheath does not substantially shrink from the heat treatment relative to the high elongation member and gathers together in an accordion-like arrangement. A tensile load applied to the lanyard stretches the high elongation member and unfolds the gathered outer sheath. The high strength outer sheath supports the tensile load when completely unfolded while the high elongation member absorbs energy as it stretches or elongates.

An image forming apparatus having a fixing device for fixing toner including wax on a transfer sheet comprising a fixing rotating member for fixing toner on the transfer sheet with a rotation thereof, and first cleaning member contacting to the fixing rotating member so as to remove melted wax on the fixing rotating member. A surface roughness Rz of the first cleaning member is not more than 1.6 μm.
摘要:
A fixing apparatus capable of preventing transfer paper from sticking or jamming, and an image recording apparatus equipped with the same. This fixing apparatus is intended to fix polymerized toner on transfer material and has a) a heating roller having a cylindrical cored bar, and a elastic layer and releasing layer provided around said cylindrical cored bar, b) a pressure roller, in contact with the heating roller, having a cylindrical cored bar, and a elastic layer and releasing layer provided around the cylindrical cored bar, c) a first guide member provided opposite the pressure roller, and d) a second guide member. provided near the heating roller without contacting thereto. In this fixing apparatus, the difference in hardness between the heating roller and pressure roller is 5 through 10 degrees in AskerC, And the hardness of the pressure roller is higher than that of the heating roller. Further, a fixing nip portion, convex-shaped on the side closest to the heating roller, is formed between the heating roller and pressure roller.
摘要:
A fixing device for use in an image forming apparatus capable of forming both-side images on a sheet by using a sheet reversing and conveying device. The fixing device has a heat applying rotary body with an elastic layer made of rubber and a toner releasing layer on top thereof, for coming into contact with and heating a side bearing an unfixed toner image of a transfer sheet; a pressure applying rotary body with an elastic layer made of rubber and a toner releasing layer on top thereof, for fixing and conveying the transfer material by coming into pressure contact and rotating with the heat applying rotary body; a drive source for driving one of the rotary bodies; and a heat applying source for heating one of the rotary bodies. The pressure applying rotary body has a micro-hardness smaller than that of the heat applying rotary body.

A color picture tube includes a vacuum envelope having a faceplate, a phosphor screen formed to include semitransparent black light-absorption layers coated on a first region of the faceplate in stripes or in a matrix, and phosphor layers of blue, red and green emitting phosphors coated on a second region of the faceplate in stripes or in dots, and an electron gun, arranged within the vacuum envelope, for emitting and focusing electron beams. End portions of the phosphor layers extend over the black light-absorption layers, thereby forming overlapped portions. Gaps are provided between the phosphor layers and over the black light-absorption layers, thereby forming light-absorption sections on which no phosphor layer is provided.

An improved wippen heel arrangement for an upright piano includes: a pillar screwed into one end portion of a piano key so that the projecting length of the pillar which projects from the piano key is adjustable; a wippen heel attached to a wippen constituting one element of an action mechanism; and a wippen joint interposed between the pillar and the wippen heel for pivotal movement about a stationary shaft, in which the thrust applied to the pillar is transmitted through the wippen joint to the wippen. Accordingly, a key touch quality which may be experienced with a grand piano can be enjoyed using an upright piano.

This invention relates to a sorter for sequentially moving a plurality of vertically stacked storage sections to a sheet reception position by a moving mechanism which is pivoted upon reception of a rotational force from a drive, and for automatically sorting sheets discharged from an image forming apparatus into the storage sections. The moving mechanism is constituted by a link body, pivotal movement of the link member allows widening of a distance betwen two adjacent storage sections, and the plurality of storage sections connected by the corresponding regulating members can be moved to the sheet reception position, thereby making the sorter compact and achieving appropriate sorting without causing jam or the like.

A process for preparing artificial bed blocks for "Shiitake" mushroom cultivation, comprising culturing lumps of spawn (mycelia) in a bottle or other containers, taking out the grown-up mycelia from the container to be kept in a closed space, keeping culturing while raising humidity in the space close to saturation to form a new aerial hypha layer on the whole surface of the lumps of spawn for higher resistance to weed fungi, then sprinkling with water over the lumps in open space to prevent weed fungi from depositing.
